Here, CNTs/C2H6O2-H2O hybrid base nanoliquid flow between two stretchable rotating discs is discussed. Significant mechanism i.e. homogenous and heterogeneous reactions effects are retained. Further impact of Joule heating, viscous dissipation and non-linear thermal radiation are also discussed. The flow and concentration as well as heat transfer are governed by the momentum and energy equations and are reduced to the non-linear system of ordinary differential equations using suitable non-dimensional variables. We have evaluated this system of non-linear ordinary differential equations numerically by using Maple -18 software. Our analysis indicates that the Nusselt number is the increasing function of Reynolds number (), Eckert numberand it decreases only for stretching parameter. At the upper disc, the surface drag force is the increasing function of Reynolds number (), magnetic parameterand it decreases for the rotational parameter. Also, SWCNT has a higher thermal field than MWCNT.
